Application tiled November 2l, 1883. (No model.) Patented in England October 4, 1883, No. 4,7525.

To all whom, it may concern,.-

Be it known that I, FRAN cis BYRNEs, a subject of the Queen of Great Britain, and a resi- 4dent of the city of Liverpool, in the county of hereby declare that the following is a description of my inventi onin such full, clear, and exact terms as to enable any one skilled in the art to which it appertains or is most nearly connected to put into practice and use the same,ref erence being had to the accompanying drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

My invention relates to the transportation of passengers, goods, substances, and :Inaterials by meansof an incline wirerope or track; and it consists in providing a convenient and enicient means for adjusting the inclination of said track and to avoid sagging, said means being applicable to all forms of gravity transportation, whether between stations on the same or on di'erent levels.

In the drawings, Figure l illustrates the application of my invention where the departure and arrival points are at the same or nearly the same levels, and Fig. 2 illustrates the application of my invention where the departure and arrival points are at different levels. I

Similar letters of reference indicate corresponding parts in the figures of the drawings.

Upon reference to Fig. 1 it will be seen that a is a wire-rope cable, which is attached at one end of the block of the raising and lowering chain b of the derrick (Z, and is attached at the other end' to the block of the raising and lowering chain e of the derrick h. The block of the chain Z) of the derrick cZ isrprovided with the back guy-rope f, and the block of the chain e of the derrick h is provided with the back guy-rope 7c.

Z is the bucket or tub by which the material or substance is conveyed from the derrick d to the derrick h.

m is a hook or shackle, which is provided with a sheave or roller, and by which the bucket or tub Z is suspcnded,and runs on thewirerope cable a.

The drawing, Fig. l, shows the tub Z in the act of traveling from the derrick dto the derrick h, and the dotted lines show the tub Z in the act of returning from the derrick 7L to the derrick d.

It will be seen that the guy-ropesf and la so draw in the derrick-chains b and c that the wire-rope cable a is prevented from sagging, and provides an inclined way from the derrick cZ to the derrick h," or from the derrick h to the derrick (Z, as required for forwarding or returning the tub Z.

In operation the chain of the derrick (Z is raised by the winch of the derrick d, (the chain e of the derrick h being in its lowered position,) and draws up one end of the wire cable a, and with it the bucket Z. The bucket Z then runs ldow-n the inclined way formed by the cable a, and is delivered at the derrick h,

the return of the bucket to the derrick cZ bei ing effected by like action of the derrick h. The length of the guy-ropes f and k is adjusted by means oi' any suitable mechanism.

Where the departure and arrival points are at different levels, I use the arrangement shown at Fig. 2. In this case I only require the derrick (Z at one end, and I use the post h in lieu of the derrick h at the higher level. The cable a travels on the guide rope or Wire g', and is raised by the chain Zn from the winch d.

The guy-ropef, adjusted by means of'asuitable winch or windlass, prevents the cable a from sagging, as this is not completely effected by the guide g, which is a fiexible rope. This guide-rope is not essential to the operation of the device; but in many placesIprefer to use it. The full lines show the package Z traveling from cZ to L, and the dotted lines show the package Z returning from h to d. By this arrangement the whole working of the apparatus is effected from the departure end d. It will be seen that my invention provides a ready means of transit across rivers and valleys and from one locality to anotherV for general purposes, and is particularly applicable for contractors and mining Work, as ameans 2.
